In the given diagram we need to choose all the names that apply to ∠1 and ∠2.
Given options :
Congruent angles
Linear Pair
Complementary Angles
Adjacent Angles
Vertical Angles
Supplementary Angels.
<em><1 and <2 are on a point on same line form a linear pair.</em>
<em>Linear pair angles are Supplementary Angels.</em>
<em><1 and <2 are adjacent to each other.</em>
Therefore,
<h3>Correct options are :</h3><h3>Linear Pair</h3><h3>Adjacent Angles</h3><h3>Supplementary Angels</h3>

Answer:
Richard= 16 years old
Teo= 7 years old
Step-by-step explanation:
Let Richard's and Teo's age be R and T years old respectively.

R +T= 23 -----(1)
R= 2T +2 -----(2)
![\textcolor{steelblue}{\text{Solving by substitution:}}](https://tex.z-dn.net/?f=%5Ctextcolor%7Bsteelblue%7D%7B%5Ctext%7BSolving%20by%20substitution%3A%7D%7D)
Substitute (2) into (1):
(2T +2) +T= 23
3T +2= 23
3T= 23 -2
3T= 21
T= 21 ÷3
T= 7
Substitute T= 7 into (2):
R= 2(7) +2
R= 14 +2
R= 16
Thus, Richard is 16 years old and Teo is 7 years old.
